UnreleasedCopy Anchor Link

ChangedCopy Anchor Link

• JavaScript: CI also tests the npm package on Node.js 26, and builds the website and publishes the package with it.
• Benchmarks also compare each binding with a loop written by hand with its language's standard library (datetime and zoneinfo, or Temporal) and checked against workclock. The numbers in the READMEs, DESIGN.md and the documentation site come from a new GitHub Actions run.
• The documentation site moved to https://workclock.karthik.nz, served from the domain root. The crates.io, PyPI and npm pages link to it.

0.1.2 - 2026-10-26Copy Anchor Link

ChangedCopy Anchor Link

• Python: PyPI shows a Python-only README, python/README.md, which links to businesstimedelta on PyPI.
• Benchmark numbers in the READMEs, DESIGN.md and the documentation site come from a public GitHub Actions run instead of a laptop, with each binding's speed-up over businesstimedelta 1.0.1 measured in the same run.

0.1.1 - 2026-10-25Copy Anchor Link

FixedCopy Anchor Link

• Python compat: HolidayRule.difference no longer raises OverflowError for datetimes whose local date is the first or last date datetime.date can hold.

AddedCopy Anchor Link

• Rust core: Schedule built from WorkDay, Break and Holidays rules, with between, add, sub, next_period and previous_period. Supports overnight and 24-hour shifts, per-rule IANA time zones and DST, as specified in DESIGN.md.
• Rust core: Weekdays, the set of days a rule applies to, and Rule, which every rule type converts into.
• Rust core: minimum supported Rust version 1.85.
• Python: typed Schedule API with WorkDay, Break and Holidays rules, between, add, sub, next_period and previous_period on timezone-aware datetimes. Accepts zone names, zoneinfo.ZoneInfo, pytz zones and datetime.timezone.utc. Errors subclass WorkclockError and the matching built-in exception.
• Python: between_many, add_many and sub_many process a batch in one call, from lists or NumPy datetime64/timedelta64 arrays, which broadcast together under NumPy's rules.
• Python: Schedule pickles and deep-copies, so it can be passed to multiprocessing workers, and workclock.Rule names the type of its rules.
• Python: type hints with a py.typed marker, and a stub for the compiled extension.
• Python: workclock.compat, the businesstimedelta 1.0.1 API on the workclock engine, which fixes overnight shifts and upstream issues 8, 9 and 10. Most code runs unchanged; MIGRATING.md lists the differences.
• Searches are bounded: a schedule without working time, or a result outside the supported range, is an error instead of a hang or a panic.
• npm package: Schedule with between, add, sub, nextPeriod and previousPeriod, taking Dates or ISO 8601 strings and milliseconds, and error classes for instanceof checks.
• npm package: betweenMany, addMany and subMany for arrays and Float64Arrays of epoch milliseconds.
• npm package: runs on Node.js 22 and later, and in browsers through a bundler or, without one, from the workclock/web entry point.
• Python wheels use the stable ABI (abi3), so one wheel per platform covers CPython 3.9 and later.
• The Python wheels and the npm package bundle the IANA time zone database.
• Examples in Rust, Python and JavaScript: when a support ticket is due and how much of its SLA has been used.
